get it here http://canberratrials.com/vidslong/canberratrials_markwartmod.mpg these things are weird!! tyres roll all over the place. i think my psi was a little low, heres a vid of the 2nd proper ride on this thing. i got sloppy towards the end (last section in the video) because it was a half an hour ride, non stop riding and im an unfit fuck. also i may look quite homosexual on this bike. enjoy my gayness Alex oh yeah, out of interest, these rocks are right out the back of my school, pretty cool as i walk past them every day.
